@article{(Open Science Index):https://publications.waset.org/pdf/10010034, title = {Functional and Efficient Query Interpreters: Principle, Application and Performances’ Comparison}, author = {Laurent Thiry and Michel Hassenforder}, country = {}, institution = {}, abstract = {This paper presents a general approach to implement efficient queries’ interpreters in a functional programming language. Indeed, most of the standard tools actually available use an imperative and/or object-oriented language for the implementation (e.g. Java for Jena-Fuseki) but other paradigms are possible with, maybe, better performances. To proceed, the paper first explains how to model data structures and queries in a functional point of view. Then, it proposes a general methodology to get performances (i.e. number of computation steps to answer a query) then it explains how to integrate some optimization techniques (short-cut fusion and, more important, data transformations). It then compares the functional server proposed to a standard tool (Fuseki) demonstrating that the first one can be twice to ten times faster to answer queries.}, journal = {International Journal of Computer and Information Engineering}, volume = {13}, number = {2}, year = {2019}, pages = {50 - 54}, ee = {https://publications.waset.org/pdf/10010034}, url = {https://publications.waset.org/vol/146}, bibsource = {https://publications.waset.org/}, issn = {eISSN: 1307-6892}, publisher = {World Academy of Science, Engineering and Technology}, index = {Open Science Index 146, 2019}, }
